A mass of 7 kg lies on a frictionless, horizontal floor. A force of 110 Newtons is applied to the mass at an angle above the positive x axis and a force of 18 Newtons is applied to the mass at an angle of 21.7 degrees below the negative x direction. If the angle for 110 Newtons is increased until the object just starts to leave the surface, what is the magnitude of the acceleration on the mass in m/s2 at this point?
